ACTUATING MECHANISM FOR AUXILIARY ENGINE UNITS.

Application filed` December 22, 1925. Serial No. 77,158.

This invention relates to devices for actuating the pump, magneto anddistributor from the internal combustion engine with which they areassociated. To attain the highest efliciency in the operation of therespective units they must each be driven at a different speed. Thepresent invention has for one of its objects to incorporate the drivingmechanism for the various units into a single structure which shall beaccessible, easily replaceable, compact and practical and by Which therespective units shall be driven at a speed conducive to their efficientoperation. Accordingly, the shafts of the various units are suitablycoupled to inde pendent shafts journaled in a housing Which may beremovably mounted on the engine and which may support the various units.The shafts may be driven, one from another, by gearing so proportionedas to obtain the requisite speed of rotation for each unit. A furtherobject of the invention is to provide driving mechanism for the unitsWhich may be readily assembled and disassembled. To this end thebearings for the respective shafts are removably mounted in openings inthe housing and covers or caps are so arranged as to permit the removalof the shafts When desired.

In order that the invention may be clearly understood the same Will noWbe described more fully With reference to the accompany ing drawingillustrating a preferred embodiment thereof and showing partly in sideelevation and partly in vertical section driving mechanism for a pump,distributor and magneto incorporated as a unit in a housing which may besupported from the engine and Which may in turn support the variousauxiliary units.

An engine to which the driving mechanism according to the presentinvention may be applied is not illustrated in the drawings, but aspiral gear rotated by such engine is shown at a and from this spiralgear the actuating mechanism for the pump, distributor and magneto isdriven. It is proposed to incorporate the driving mechanism as a unitarystructure in a housing'indicated as a Whole at t). The housing isprovided with a flange h by Which it may be removably secured to theengine adjacent the gear e. The pump is carried directly on the housingby means of the flange The pump is not shown but a fragmentary por-`bearings j,

tion of its rotor shaft is indicated at c Which is coupled to what maybe termed the first shaft Z `iournaled in removable bearings e, in thehousing Shaft Z is driven from the spiral gear 0. by a spiral gear gWhich is keyed to it and which is so proportioned as to cause therotation of the shaftfl at the most efficient speed for the operation ofthe pump. The magneto 7a. is shown as carried upon a bracket t integralwith a closure b for the opening b5 through Which shaft (l and thebearings may be removed from the housing. The magneto is operativelyconnected as by a flexible coupling y7i. with a second shaft el alsojournaled in removable in the housing h, this shaft being remou'tble byaxial movement to the left, as viewed in the drawing, through theopening Z9 closed by the cap If. The magneto is driven at a higher rateof rotation than the pump. Consequently the spiral gear Z carried withshaft e' which meshes With gear g is of a smaller' vdiameter than gear gso that the ratio is such as to obtain the requisite higher speed. Theopening o8 through which shaft 71 extends for engagement with thecoupling 71. may be closed by an extension o integral with the bracketIf a distributor' m is also to be driven. by the driving mechanism itmay be rcmov ably secured to a flat surface b9 at the top of housing band the distributor shaft m may extend downwardly into a Well h1@ Withinthe housing to be rotated from one of the shafts, say shaft z'. The endof shaft m. carries a spiral gear n, meshing With a spiral gear ocarried on a sleeve o keyed to shaft e' and these tivo gears may be soproportioned as to obtain the desired speed of rotation for thedistributor. If any one of the auxiliary units, for instance, thedistributor, is not to be driven from the driving mechanism, a cap maybe substituted therefor and secured, as by the boit m2.

In disassembling the driving mechanism after the driven auxiliary unitsare removed either before or after the housing has been removed from theengine structure the closures and 57 are removed. Shaft ai may then bemoved axially to the right through the opening h5, the bearing alsopassing through the opening and the shaft passing through the gear g,the key d passing along the keyvvay g. After the shaft is clear of thegear the gear may be passed downwardl vout of the housing through theWell 111. haft' is similarly removed by moving `it to the left, beingdisengaged from the gears 1l and 0 in a manner similar to thedisengagementof shaft cl. To remove the distributor it is, of course,merely necessary to disengage bolt m2 and raise the distributor invertical direction thereby drawing the shaft m and gear a out of thewell blo through the opening through which shaft m enters.

By the construction described various auxiliary units associated with aninternal combustionengine may be driven at a predetermined speedconducive to efficient operation and the actuating mechanism isincorporated vinto a compact, easily demountable, unitarystructurewvhich is supported i removably from the engine and in turnsupports the respective units.

The invention has been described a" associated with the pump,distributor and magneto of an internal combustion engine but obviouslydevices other than those enumerated maybe driven by the mechansm.

Various modifications in the arrange ment and proportion of parts Willoccur to those skilled in the art and no limitation in the use or thecombination of elements is intended by the foregoing description andillustration except as indicated by llal accompanying claim.

Vhat I claim is:

In a driving mechanism for auxiliary de vices including pump, magneto,and distributor drive shafts, Va unitary housing supporting said shafts,means for securing the housing removably to the housing of a powersource, means to support the pump shaft removably `in the housing, agear earried by the pump shaft and engaging the power source means tosupport the magneto shaft removably in the housing and parallel to thepump shaft, a. gear on the magneto shaft meshing With the gear on thepump shaft, means for supporting the`distributor shaft removably in thehousing at right angles and offset with respect to the magneto shaft,means to drive the distributor shaft from the magneto shaft, a removablecap on the housing providing access to the magneto shaft, and aremovable closure for the opposite side of the housing, said closureproviding access to the pump shaft and a bearing` for the magneto shaftand having an extension for mounting the magneto, whereby the entireassembly is mounted as a unit.
